Vimplication filed October 1,5, 1325. Serial No. 62,607.;

This invention relates to new'and useful improvements Vin padlocks. i

The primary object of the invention is to provide iinproved'forins ofpadlocks of the sliding shackle type having novel means for holding theshackle in its closed or locked position. Y

A r,further object' of theinvention' is'the provision of novel means forreleasing the shackle from its holding nieansk" Other 'objects andadvantagesof the invention will he apparentf'during the coursey partlyin elevation, of the' structure shown in Figs. 1 and'2', v

A shackle 1.3 is associated with thispad= lock and has itsv oppositelegs18a`forinedg with transversely alined'l notchesVV into which the springenlargements 10 are i'n-r tended to project, when the 'shackle is `in'serted'l into thecasing 5 through the open-` the shackle 13 includes aAbody portion 15` 'ings 7, for preventing. the withdrawal ofthe i whichis formed with the tuhularseetion 16 and thel U-shaped end portionl?,the sides of this U-shaped end portion being provided Vwith alinedapertures 18 which are also axially a'lined with rthe'tuloularportionl'?.

A sliding rod 19.' is inserted `through' 'theQ 1 tuhularportion 16 andlias' its' end `portion 20'screwthrea'ded and located within thealinedapertures 18.

ing the ring like abutment 64 spaced inwardly from its inner end. Thespring 65 encircles the pin 63 and bears at ,one end against theabutment 64 and at its other end against the inner face of the disk 49.It will be seen that this spring lfunctions to force the inner extremityof the pin toward the disk 60. The post 50V has an operating head 66formed on itsouter end While one face thereofis provided with theindenture 67. This indenture registers or is in alinement with the notch61 and is intended to indicateV the location of the latter. Figure 12shows the side 53 of the shackle 54 as having a cross 67 formed therein.This cross 67 is merely intended to distinguish the side head 66 of thepost 50 for locating thedisk notch 61 in alinement with the lug 57 ofthe shackle leg 53. This lug may then be passed through the notch 61 forlocating the lug inwardly of the disk. The disk may then be rotated fordisalining the lug- 57 and notch 6l and the disk should be moved untilthe notch 6l registers with the inner extremity of the pin 63. Thespring 65 will then force this extremity into the notch 61 and the disk60 will be prevented from rotating until the pin extremity is extractedfrom the notch. To unlock the shackle 54, the above operation is merelyreversed.

Itis to be understood that the forms of this invention herewith shownand described are to be taken as preferred examples of the same, andthat various changes in the shape, size, and arrangement of parts may beresorted to without departing from the spirit of the invention or thescope of the subjoined claims.

Having thus described the. invention, I

claim ,l

l. In a padlock of the type described, a casing having a pair of shackleleg receiving openings, a Ufshaped shackle having a notch formed in eachleg thereof, a V-shaped leaf spring connected at its base to the casing,

an enlargement carried by each end of the spring and adapted to enterthe vnotches in the shackle legs, and a key insertable into the casingfor connection with the enlargements to force the latter toward eachother and out of the notches. i

2. In a padlock'of the type described, a ycasing having a pair ofshackle leg receiving openings, a U-shaped shackle having a notch formedin each leg thereof, a `V-shaped leaf spring connected at its base tothe casan enlargement carried by each end of JOSEPH SZAKCS.
